This case is equipped with an intelligent infrared anti-climbing device: when someone climbs the door, the system will immediately alarm to ensure the safety inside the door. Special profiles: Adding different geometric shapes of ribs to high-hardness zinc-aluminum alloy profiles can greatly enhance their strength. The surface has been treated by special electrophoresis. It has unlimited luster, is not easy to stick to dust, is not corroded by polluted gases, is not easy to rust, and has a new guarantee period. long

An intelligent infrared probe anti-collision device is also installed: the door will automatically return to operation if it encounters a person or foreign object 30-50cm away during the closing process, thus ensuring the safety of vehicles and pedestrians. Standard structure: The inner space of the door row (i.e. the distance between the two adjacent curved main pipes at the front and rear, excluding the size of the main pipe) adopts the standard size of the telescopic door 320mm (referring to the most advanced technology in the world) to ensure that the cross pipe is the strongest and greatly reduces the operation noise
